The Cisnes River is a river located in the Aysén del General Carlos Ibáñez del Campo Region of the Chilean Patagonia. It runs in east-west direction from the mountains near the border to Argentina and empties into the Pacific Ocean, near the town of Puerto Cisnes at Puyuhuapi Channel. Its characteristic turquoise-blue color is due to the glacial sediments deposited in it. Moro River and Pinchado River are some of the major tributaries of the river.
